Hello Mylee,

I'm very much involved in a project to describe Dutch public libraries in Wikidata : https://www.wikidata.org/wiki/Wikidata:WikiProject_Netherlands_Public_Librar... (bit messy, work in progress)

Example item: https://www.wikidata.org/wiki/Q1902577

Overview of Properties + data quality control queries : https://www.wikidata.org/wiki/Wikidata:WikiProject_Netherlands_Public_Librar...

(I based this project on the work done by Simon Cobb (https://www.wikidata.org/wiki/User:Sic19) on Welsh libraries: see his user page under " SPARQL queries")

Please note the difference between * Library organisations (like https://www.wikidata.org/wiki/Q59961895), which can have multiple branches * Library branches (like https://www.wikidata.org/wiki/Q61718918), that are part of a library organisation I've coupled these relations using the PartOf (P361) vs. HasPart (P527) relations, but for instance Simon used Operator (P137)

I've matched the geo coordinates (P625) to OpenStreetMap nodes: eg. in this item https://www.wikidata.org/wiki/Q61718919 --> P625 --> Source reference --> https://www.openstreetmap.org/node/2676963119

As a side note: I notice that quite often (I'm also doing it myself every now and then) the concepts of a library branch (Q11396180, an "organisational thing") and a library building (Q856584, an "architectural thing") are combined into one single Q-number, while ideally these are two distinct concepts (which should/could have their own separate Q-items....

Hopes this helps...

Kind regards Olaf Janssen
